18in #4 Line -4 Str/-4 Str 5pk

The Allstar Performance 18-inch #4 line brake hose 5-pack (SKU ALL46400-18-5) is a purpose-built hydraulic assembly designed for high-pressure brake systems in performance vehicles, racing applications, and custom builds. Each hose features 4 AN straight female-to-female connections and measures 18 inches in length, providing the precise fitment required for routing brake lines through engine bays and chassis tunnels without compromise or adapter complexity.

Construction centers on a braided stainless steel outer jacket paired with PTFE (Teflon) lining, a combination that resists corrosion from brake fluid exposure and vibration damage while maintaining burst strength under sustained pressure cycles. The stainless braid sheds heat and stands up to both synthetic and conventional brake fluids without degradation. The 4 AN size accommodates flows typical of dual-circuit systems and delivers reliable performance in both street and track environments where thermal cycling and component movement are constant variables.

A five-pack format addresses multiple-line applications—dual fronts, dual rears, proportioning valve distribution, or component redundancy—reducing the need to source individual hoses from multiple suppliers. This is the working setup for serious enthusiasts: fabricators, performance shops, and builders who value consistency across a complete brake system assembly. The straight-female connections eliminate fitting direction confusion and simplify female-to-female unions without additional swaging or crimping operations in the field.

Allstar Performance has built its reputation on race-proven hydraulic components. This hose line meets SAE J343 standards for automotive brake hose construction and is engineered for systems operating at pressures well above street-car baseline, making it equally at home in road-course competition or resto-mod street applications where reliability cannot be compromised.
